16.1.4 Notes on power saving functionality

(1) Notes on Power Saving Function Using Scheduling

• To use the same power saving functionality during a normal time range and a scheduled time range, perform the setting for both time ranges.

  Example

  Suppose you use the shutdown configuration command to turn off a particular port during a normal time range. If you want to turn off that port during a scheduled time range, you must include it in the parameter of the schedule-power-control shutdown configuration command.

(2) Notes on errors in the start and end times of the schedule period

Because scheduling uses a software timer, a situation such as a high CPU load might cause a time lag before the set start or end of a scheduled time range takes effect. The delay should be less than one minute. Also, depending on the network configuration, there could be a time lag before communication with the port resumes at the end of a scheduled time range in which the port's power supply has been turned off. Allow a certain margin when you schedule power control.
